Abstract:
A molding apparatus for molding a recorded disc includes a pair of mold plates adapted to form a mold cavity therein and a center hole forming pin slidably mounted in one of the mold plates. The center hole forming pin is larger in diameter than the hole to be formed and has a projection on its end which is of a diameter equal to the hole to be formed and a length about one-half the length of the hole to be formed. The other mold plate includes a projection extending therefrom of a diameter equal to the diameter of the hole to be formed and a length one-half the length of the hole. In the molding of the disc the projection on the center hole forming pin engages the projection on the other mold plate to form a hole in which a flash is spaced from the edges of the hole.
